Dollars And Sense: The Financial Case For Automation
By Doug Johnson, Emerson Process Management Power & Water Solutions

Nuclear Reaction: PE Pipe Finding Increased Use
By Jim Craig, P.E., McElroy Manufacturing
Polyethylene (PE) pipe is not a new product in the United States, or even the rest of the world. In Europe, it is the piping material of choice for water, sewer, and gas distribution systems. In the United States, about 90 percent of new gas distribution installations are made with PE pipe. The pipe's notoriety has been growing domestically in the sewer and potable water markets as well.


Denitrification For Strict, Varying Nitrogen Limits
By Severn Trent Services
The cities of Littleton and Englewood, CO, just south of Denver, share a wastewater plant — the Littleton/Englewood Advanced Wastewater Treatment Plant (AWT) — located in Englewood. The 50-MGD Littleton/Englewood AWT plant serves more than 300,000 residents in the Denver metropolitan area. The facility also receives sewage from 21 districts within a 75-square-mile service area. Plant process upgrades, including enhancing nitrate removal with a new in-plant recycling system and new denitrification filters, were needed to accommodate the area's fast growing population.
